I have just converted my old 36Mhz Flash 5 SX computer Radio TX to 2.4Ghz, using the Hitec Spectra 2.4Ghz module.

Preliminary tests reveal that the performance is equal to the same module's performance in an Optic 6, and Eclipse 7 radio.

If anybody is interested, I can post photo's and instructions of this conversion.

I believe the same connections apply to Hitec's Laser 4 and Laser 6 radio's as well.

The reason I am converting to Hitec stuff is because if you use the Optima 6 and Optima 7 receivers, in conjunction with the Hitec Spectra module, you can program the module to let you know when your receiver battery drops to a specific voltage. Can be used for both NiMH and LiPo batteries up to 35 volts. This sort of telemetry with Spektrum, costs you about $150 extra, per system, if you have an existing DX7 system. Too expensive in my book! And I have 4 Spektrum DX7 systems.

If anybody wants to buy a mint condition Spektrum DX7 system with an AR7000 receiver send me an email. Asking price is $450 delivered.

My next project will be to convert my 36 mHz Multiplex C ockpit SX to 2.4Ghz, using the same Hitec module. The 7 channel C ockpit SX is one of the sexiest radio's I have ever come across, and to be able to use it once again, with the latest technology, will be a dream.
